Mahle Rings Performance HV385 Steel Top 3.779 x 1.2MM .133RW Moly Ring Set

Mahle OE is known for making reliable engine parts, and their Performance HV385 Moly Ring Set is a solid option when you're rebuilding an engine. These rings are designed to seal the combustion chamber effectively, helping your engine run smoothly and efficiently. They are made from steel with a moly face, which is a common and durable choice for piston rings.

This particular set features a 3.779-inch bore size and a 1.2mm top ring thickness, with a .133-inch ring land width. The moly coating on the top ring helps reduce friction and wear, especially during the critical break-in period. This makes them a good choice for many performance-oriented engine builds where durability and proper sealing are important.
